Very good experience from the communication with quick responses from Kai, his apartment is in a brand new luxury tower who own an amazing big swimming pool . No disturb by neighbors, sometimes we felt like alone with my girlfriend in this 48 floor tower!
You can go eyes closed, just a little problem with water in the shower who always change from cold to very hot and have to be very careful. I saw that in a few luxury hotel in Thailand, I'm thinking about bringing thermostatic faucets from Europe at my next trip :-)
Without this little problem who will be fixed soon I guess everything has been perfect!
